  2. 6. Fabrication and Characterization of Aluminum Single Electron Transistors for Scanning Probes

    Author : Henrik Brenning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radio frequency single electron transistor; scanning probe; charging energy; nano fabrication; noise; scanning SET; SET; cantilever; AFM; RC-product; micro mechanics;

    Abstract : The main objective of the work presented in this thesis was to fabricatescanning single electron transistor probes that operate at pumped liquid heliumtemperatures. This required single electron transistors (SETs) with low resistance (R_) and relatively high charging energy (E_C), and the technology tointegrate SETs onto probes. READ MORE

  4. 7. Probing Electron Collisions in Nanostructures

    Author : Fikeraddis Damtie; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron-electron interaction; Time dependent dynamics; Multiple Exciton Generation; Two dimensional spectroscopy; Fysicumarkivet A:2017:Damtie;

    Abstract : This thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. READ MORE

  5. 8. Nanoscale YBa2Cu3O7-δ devices -Searching for a subdominant order parameter using a single electron transistor

    Author : David Gustafsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grain boundary; Josephson junctions; YBCO; single electron transistors; high temperature superconductivity;

    Abstract : The microscopic origin of High critical Temperature Superconductivity (HTS) is still an open issue in condensed matter physics. It is believed that by exlporing the quasiparticle energy spectrum one can learn about the mechanism promoting the superconducting state. READ MORE

  6. 9. First principles simulations of electron transport at the molecule-solid interface

    Author : Hao Ren; Yi Luo; Nicolás Lorente; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; first principles; electron transport; solid surface; inelastic electron tunneling; Quantum chemistry; Kvantkemi;

    Abstract : In this thesis I concentrate on the description of electron transport properties of microscopic objects, including molecular junctions and nano junctions, in particular, inelastic electron tunneling in surface-adsorbate systems are examined with more contemplations. Boosted by the rapid advance in experimental techniques at the microscopic scale, various electric experiments and measurements sprung up in the last decade. READ MORE

  7. 10. Quench-Condensed Metallic Clusters Studied by Single Electron Tunneling

    Author : Andrey Danilov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Using angle deposition through conventional electron-beam lithographic masks as the sample resistance was measured in situ, we defined constrictions with widths and lengths of about 5 nm in thin (1-3) nm granular films. The nominal film thickness in the constriction could be varied stepwise by in situ film depositions, changing the grain size and the configuration of the tunneling paths. READ MORE
